The present inventionrelates to composing room machines. I a More particularly the present invention relates to improvements in machines suchas I are usedin the composing rooms of printing establishments. The present invention contemplates a combined machine having the functions of a router, type-high machine, drill, jig-saw and broacher, and has for one of its objects the provision of a machine occupying relatively small space, which is simple and sturdy in construction and which is well adapted to meet the needs of commercial service.

A further object is to provide an improved router or type-high machine which is readily adjustable and which is convenient to use.

' A further object is to provide an improved type-high machine which may be accurately 520 and conveniently adjusted regardless of wear upon the cutting tool. A further object is to provide an improved jig-saw or broacher whichis convenient in use, particularly with relation to convenience in changing the cutting blade.

Further objects will appear as the description proceeds.

The numeral 10 indicates a standard mounted upon a base 11. Bolted or other-1 wise secured at the upper'extremityof the standard 10 is a member '12 provided with two pairs ofjaws or armsw The'upper and lower jaws 13 and 14, respectively, on one side of the member'12 comprise tional elevation taken through the jig-saw n a the cooperating aws of a j1g-saw,broacher or the like. The

jaws 15 andl6 on the opposite side of the member 12 comprise the jaws of a router. type-high machine, or the like.

Referring first to the j ig-saw portion of the. 1 machine, a motor 17 is supported in any preferred manner upon the standard -10, which motor is, provided with a pulley 18, which through a belt 19 drives the pulley 20, which pulley 20 is secured ,to the shaft 21, having bearings 2222 supported by the lower jaw 14; of the jig-saw portion of the machine. ,The extremity of the shaft 21 spaced from the pulley 20 is provided with the eccentric or crank 23 having the pin 24 which drives the crank arm 25. Said crank arm 25 drives the pin 26 secured to the cross head 27, which is secured upon the outer extremity of the jaW 14in a manner to permit a reciprocating movement in a Vertical direction. The crosshead27 is provided with the hook 28 adapted toengage over one extremity of the saw blade 29. The other extremity of the saw blade 29 is adapted to 'be engaged by the hook 30 carried by the slide 1. 31, which slide is supported to have a reciproeating straight line movement upon the outer extremity of the jaw 13.v Said slide 31 'Is provided with the roller 32 adapted to 'be engaged by the outer extremity of the lever 33, which lever 33 is pivoted to have a rocking movement with the shaft 34 as an axis. A coil spring 35, which may be anchored upon the abutment 36, biases the lever 33 in a clockwise direction, movement in said direction be- .ing limited by reason of the engagement of the outer swinging end of said lever 33 with the roller 32 of the member 31, movement upwardly of which is limited by reason of the connection of the saw blade 29 with the member 27, which is pinned to the crank arm 25. The numeral 37 indicates a handle which may be swingingly mounted uponjthe shaft 34 and which projects above the jaw 13 in a position in which it may be readily grasped. Said handle includes an arm 37 A parallel with but spaced from the shaft 34, which arm 37A overlies the lever 33. Said handle 37 provides means whereby he outer-swinging end of the lever 33 may be depressed in opposition to the spring 35, whereby the saw blade 29 1 turning movement to said shaft.

may be readily changed. The numeral 38 indicates a work table carried by the jaw 14, which work table is apertured as indicated by the numeral 39, whereby to permit reciprocating straight line movement of the saw blade 29.

Referring now to the router or type-high portion of the machine, the upper jaw 15 is formed to slidably receive a motor 40, which motor is disposed with its axis vertical. Said motor 40 is provided with the collar or chuck 41 adapted to grip the router or typehigh tool 42. The numeral 43 indicates a table for supporting work to be operated upon by the tool 42. Said table 43 is carried by the shaft 44, which shaft is carried by the jaw 16 in a manner which will be described presently. A stud or studs 44A are provided for holding the table 43 against displacement about the axis of the shaft 44, .while permittingvertical movement of said table 43. The shaft 44 is adapted to have sliding movement in a vertical direction within the sleeve portion 45 at the extremity of the jaw 16. Said sleeve portion 45 is cut away as indicated by the numeral 46, to provide access to the shaft 44, the adjacent side of which shaft 44 is provided with the rack teeth 47. Engaging with the rack teeth 47 is the gear 48 secured to the shaft 49, which is rotatably supported by the bracket 49A, which is releasably secured to the jaw 16 at the bottom of the sleeve portion 16 thereof, screws 49B49B being illustrated as the holding means. Rocking movement is communicated to the shaft 49 by means of the segment 50, said segment 50 being controlled by the treadle 51 operating through the cable 52. Said treadle 51 is pivoted to the standard 10, as indicated by the numeral 53. It will be clear that when the outer extremity of the treadle 51 is depressed, the gear 48 will be rotated in a counterclockwise direction as the parts are viewed in Figure 4, resulting in the lifting of the shaft 44 and the table 43. In order to govern the limits of travel ofthe table 48, adjustable means are provided which will now be described. The numeral 55 indicates a shaft having the screwthreaded portion 56 and the second screw-theaded portion 57. Intermediate of the screw threaded portions 56 and 57 is the shoulder 58 adapted to rest against the bracket 49A when the table 43 is in its lowermost position. The screw-threaded portion 56 of the shaft 55 has engagement with the threaded axial aperture 59 within the shaft 44. A hand wheel 60 is provided'at the lowerextremity of the shaft 55 for communicating Theshaft 44 will be held against rotative movement whereby turning of the shaft 55 will communicate a straight line movement to said shaft 44, whereby the lower limit of the table 43 i will be determined. Figure 4 showsthe shaft 44 in engagement with the shoulder 58, this being the lowermost position of said shaft 44. The screw-threaded portion 57 of the shaft 55 is provided with the nut 61, which nut is split in a plane transverse to the axis of the shaft 55, as indicated by the numeral 62. A screw 63 is provided for adjusting the grip of said nut 61 upon the screwthreaded portion 57. By varying the position of said nut 61, the upper limit of travel of the shaft 55 is determined.

In order that vibration of the table 43 may not cause a creeping of the shaft 55 whereby to result in the lowering of the table 43, means are provided for preventing turning movementof the shaft 55 relative to the shaft 44. By reference to Figure 5 it will be noted that the screw-threaded portion 56 of the shaft 55 is provided with a radial hole 64, which hole is adapted to receive the button 65, which button is spring-pressed outwardly by the spring 66. The outer extremity of the button 65 is toothed, as indicated by the numeral 67, to conform to the threads of the aperture 59 within the shaft 44. By reason of the fact that the button 65 is spring-pressed outwardly against'the wall of the aperture 59, creeping of the shaft 55 is effectually prevented. It will be understood, of course, that by. adjusting the nut 61, theworkman may accurately predetermine the upper limit of travel of the table4-3. This feature is useful in routing out an enclosed area, the routing being done with the treadle depressed (table up), the treadle being allowed to rise when the boundary of the routed out portion is to be passed over.

Certain, features of the present invention applicable to adjustment for type-high planing will now be described. A' printing plate should preferably have a flat baclgand usually has a standard height of .918 inch or varying from said standard by a predetermined amount. According to the present invention absolute accuracy is obtainable in type-high planing regardless of wear inthe planing tool; In order to provide accurate adjustment, an indicator rod 68 is provided, which indicator rod is best shown in Figure 2. Said indicator rod is mounted to swing about the axis of thefvertically disposed shaft 69 and is provided'with the indicator 70 for indicating variations in the vertical position of the rod.68. The shaft 69 is rotatably disposed within the boss 71 located upon the jaw 15, andis resiliently'held inposition by means of the spring 72. Mounted upon the'shaft 69 is the arm 78,said arm being adjustable along the shaft 69, which arm yieldingly supports the rod 68.

In operation, a printingplate is supported in a vise 74, which is supported upon the table 43, and a planing cut is made on the rear side of said printing plate by thetool 42 to mark the cutting plane of said tool.

Said plate is then placed under the vertically disposed indicator rod 68. Said rod 68 is so disposed that the spring urging it clown- Wardly is under slight tension when said indicator rod is bottomed on said planed surface. The scale on the indicator 70 is set so that zero corresponds with the needle 7 5 of the indicator 70, which needle is movable in response to movement in a vertical direction of the indicator rod 68. The zero position of the cutting plane of the tool is therefore determined. A standardblock may be positioned between the plane surface upon which the printing plate is supported and the bottom of the'indicator rod, and the hand wheel 60 is turned until the needle reads zero, or a predetermined variation from zero, as desired. The table is now in proper position for a planing cut at the predetermined height. Any preferred means may be provided for locking the hand wheel once it has been set, the button 65 being indicated for this purpose.

It is intended to cover all modifications that fall within the scope of the appended claims.
